FILTER.l

SPECIFICATION forming part of Letters Patent No. 57 2,136, dated December 1, 1896.

Application iiled July 18, 1895.

To all whom t may concern:

Be it known that l, GEORGE STITES, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Filters, which improvement is fully set forth in the following specification and accompanying drawings. i

My invention consists of anovel construction of filter which is adapted to be built up in sections, the dimensions of the same being readily increased or diminished according to requirements, provision being made for successively filtering the incoming water and for regulating the flow of said water throughout the different compartments of the filter.

It further consists of a novel manner of constructing and supporting the iilterin g dcvices whereby the latter can be readily raised or adjusted so as to be cleaned according to requirements.

It further consists of a novel construction of gate which is especially applicable to the above iilter.

It further consists of novel details of construction, all as will be hereinafter set forth.

Figure 1 represents a plan View of a filter embodying my invention. Fig. 2 represents a longitudinal section on line a; Fig. 1. Fig. 3 represents a section on line y y, Fig. 2. Fig. 4 represents a front elevation of Fig. 3. Fig. 5 represents afront elevation of Fig. 2, showing the inlet and the manner of supporting the protecting-gratingtherein. Fig. 6 represents a front elevation of one of the gates and means for operating thesame, the iiooring and sides of the iilter being shown in section. Fig. 7 represents a section on line oc', Fig. 6, a portion of the figure being shown in elevation. Figs. Sand 9 represent front and side views of a hinged frame and the manner of supporting the same whereby access is had to the interior of the filter, and the iiltering devices therefor can be cleaned. Fig. 10 represents a section on line .a z, Fig. 1, showing the frame for supporting the screens and gratings. Fig. 11 represents a sectional view showing the manner of assembling the filtering-cloths and holding the same in position. Fig. 12 represents a sectional view of a cleaning attachment and a valve therefor.

Serial No. 556,345. (No model.)

Similar numerals of reference indicate corresponding parts in the several figures.

Referring to the drawings, 1 designates a filter, the same being composed of the sides 2 and the iioorng' or base portion 3, the above parts being held together and braced in any suitable or convenient manner. The inlet end'of the filter, which in the present instance is at the left in Figs. 1 and 2, has a partition 5 therein, adjacent to which is suitably supported the protection grating G, which prevents obstacles of a large or objectionable character from passing through the passage 7 into the chamber 4. i

8 designates an arresting-screen which is located adjacent said grating 6, and may be supported in position in any suitable manner, as indicated in Fig. The water after passing through said grating 6 and arrestingscreen 8 enters the chamber 9 and passes into the chamber 13 through the opening 10, which latter is controlled by means of the valve 11, which is actuated by the stem 12, as will be hereinafter explained.

From the chamber 13 the Water passes upwardly through the wooden grating 14 into the chamber 15, the water being iiltered and strained in its upward passage by means of lthe filtering device 16, which is suitably hinged at 17, while thel manner of assembling the iiltering-cloths, &c., will be understood from Figs. 8, 9, 10, and 11. The Water after passing through the chamber 15 passes on through the opening 1S into the chamber 2O,y said opening 18 being controlled by means of the valve 19. From the chamber 20 the Water passes upward through the filtering device 22, Whose construction will be hereinafter explained, into the chamber 24, and

thence through the passage 23 into the chamber 25, and from thence through the filtering device 27 into the chamber 28, and then through the passage 29, controlled by the valve 31, into the chamber 30, which may be provided with filtering devices similar to those already described, or may lead into a suitable reservoir, if desired.

It will be noticed that the chamber 24 is twice the area of chamber 15, and that the chamber 25 is three times the area of the chamber 15, the next chamber or chambers in-the series increasing in a proportionate ratio as required, whereby the greater quantity of water in the filter is in a condition for use, and is less stirred or agitated by the filtration in the inlet end of the same. It will furthermore be evident that instead of one series of compartments, as shown in Fig. 1, two or more may be placed side by side, as indicated in Figs. 4 and 5, the number of compartments being increased or diminished according to requirements.

The mechanism for actuating the Valves and the construction of the latter will nowbe described, it being understood that all the valves or gates 1l, 19, 26, vand 31 are substantially the same, and therefore the description of one will suffice for all. The said gate l1 is provided with a facing of hard rubber 32, which is wedged or otherwise secured into saidgate and has its bearing upon the seat or ypartition 10X, which in the present instance separates the chambers 9 and 15, and said gate 11 has suitably attached thereto the hollow tube 12, to which is secured a nut-34, the threaded stem 33 engaging said nutand being adapted to work freely -in said hollow tube 12, said stem being inclosed by the casing 35, which is sustained above the gate upon any suitable support.

36 designates a cap mounted on said casing 35 `and having the neck 37 passing freely therethrough, said stem 33 being prevented from upward movement by the engagement of the shoulder 38 with the under side of said cap 36.

39 designates-a bevel-gear which is mounted on the top of said stem 33, and is engaged by a similar Agear 4l, mounted on the shaft 40, which latter may be actuated by any suitable means, as bya wheel 42, the -preferred construction being seen in Fig. 6, in which each end of the gate is provided with a threaded stem and means for actuating the same so that the ends of said gate will be simultaneously raised.

In Figs. 8,9, 10,and 11 are shown-detail views of the Iltering devices and means for obtaining ready access to the same and to theinterior Vof the filter and for Vremoving the iil-tering-cloths when desired.

44 vdesignates arod or tube which passes up through the beam 44X, the lower portion of said rod 44 having -attached thereto a T 45, from which extend in -either direction the nipples 46, each of said nipples having an engagement therewith, the Ts 47, to which are secured the nipples 4S, which engage vthe other Ts 49, the -latterhaving attachedthereto the portions 50 of the frame 16, which is made of pipe or tubing, as willbe understood from Fig. 10,said framehaving'the end por-- tions 43 and being of a rectangular or-other shape, and having the screen 43X extending between the walls of said frame.

In Fig. 11 is shown one manner offholding the filtering-cloths inlposition, 14 designating a wooden grating, as before, while 51 designates said filtering-cloths, the latter being placed, as seen in said figure, so' that their points of junction will overlap, the same being held in position by means of the bar 52, of wood or other material, which is supported across the laps, one end being secured in one of the partitions, while its other end is clamped down to hold the filtering-cloths in the desired position. It will be noted that in the compartments 15 and 24 the water passes upwardly from said chamber through said grating, while from the chamber 27 it passes downwardly, and to `provide for this provision is made, as will be explained.

In Fig. 1 the screws at the end of the gates are shown as being operated each by a separate hand-wheel, and in Fig. 6 as operated S, 9, and 10. In the second section 24 alight I wire grating is laid vupon the wood grating, then one or more layers -of finer filteringcloth, and then upon the whole is placed the hinged frame, as seen at the-rightof Fig. 10. In the third' section 25 the hinged frames shown in Fig. 10 may be omitted, rif desired, and in place of the same only fine filteringcloths employed, as shown in Fig. 1-1, the

same being placed 4upon the vgrating 14 with or without an interposed screen, and `being overlapped and =held in position, `as seen in said Fig. 11.

When it is desired to clean the filter, the

device shown in Fig. 12 is Aemployed,fidesignating a trough or channel under each compartment, the entrance .to veach being controlled by the valve 61, which 4has a stem passing 'through the yoke '62, by whichisaid valve is moved toward or away from lits seat, said channels 60 being-in communication with each other and leading to asewer orother conduit, the whole apparatus Ibeing thus readily cleansed lor flushed when desired byfopening said valves 61, AWhile accesscan be had to the interior by raising the hinged frames, it .being further evident that when it is-desired `.to use the latter in the vcompartment 25 the ltering-cloths are placed upon the hinged frames, as seen to the left-of Fig. .10, kwhile in t-he Vcompartments 15 and 24 the `hinged frames are placed over said filtering-cloths, as seen in Fig. Y10 at the right.

When fsaid and the arresting-strainers 8 passes into the chamber 9, and thence in succession into the chambers 13, 15, 20, 24, 25, and 28, it being successively filtered as it passes through the screens and cloths, as has been explained, and when it is desired to clean the apparatus or to remove the material strained from the water it isonly necessary to lift the iron frame 43, the same swinging readily on the joint 17, as will be evident, and access can then be readily had to the interior at all times, the manner of flushing or cleaning out the sediment from the floor of the device having` already been described.

Every part of the lter is readily accessible and the dimensions of the same can be increased or diminished according to requirements, and in case of injury or damage to any of the parts the same can be readily replaced, as is evident.

By having the successive chambers of increased size and the straining-cloths of increased iineness the coarser matter is separated at the entrance of the filter and each successive iiltration is of the iiner particles, and generally of less matter.

Having thus described my invention, what l claim as new, and desire to secure by Letters Patent, is-

1. A iilter having a protection-grating at its inlet, an arresting-screen adjacent said grating, and provided with series of upper and lower chambers of increasing dimensions, movable frames suitably supported in each of said chambers, filtering devices mounted upon said frames, dividinggates for said chambers, and separate discharge-valves for each of said lower chambers, each of the chambers of each series communicating with a chamber of the other series, said parts being combined substantially as described.

2. A iilter, having suitable sides and iiooring, a protection-gratin g, an arresting-screen,

a series of compartments, in communication therewith of increasing diameter, a grating in each of said compartments, screens and filtering-cloths supported upon said grating and hinged frames having wire gratings or screens attached thereto, for holding said cloths in position, substantially as described.

3. Inailter, aprotection-'grating, an arresting-strainer, a series of valved compartments, gratings thereon, hinged frames over said gratings, filtering devices supported upon said frames, in combination with means for cleansing said compartments, substantially as described.

4. In a filter, suitable gratings, the supporting-rod 44, the connections 48, pivotally mounted thereupon, the frame 43, attached to said connections, in combination with wire screens mounted on said frame, and cloth interposed between said screens, substantially as described. p
